M073900100028 For neutrons correlated with protons - array of M073900100029 plastic scintillator time-of-flight detectors, M073900100030 deployed on the opposite side of photon beam M073900100031 between polar angles of 28 and 148 deg, the M073900100032 azimuthal angular coverage was always 13.5 - 22 deg. M073900100033 ERR-ANALYS (ERR-S) Statistical errors due to random sampling of M073900100034 the experimental kinematics. M073900100035 COMMENT The photon asymmetry of the 12C(g-pol,pn) reaction M073900100036 has been measured for separate missing energy M073900100037 regions corresponding to the ejection of nucleons M073900100038 from (1p)**2 and (1p)(1s) shells.
